Patellar Valgus: When to Consider Arthroscopy - Orthopedics

More Info

---

Patellar valgus, or patellar malalignment, refers to the outward angulation of the kneecap (patella) relative to the femur. This condition can lead to various knee problems, including pain, instability, and potentially cartilage damage if left untreated. Your concern regarding the significant valgus angle observed in your X-ray and the potential for cartilage wear is valid.
When considering whether to proceed with arthroscopy, several factors come into play. First, it's essential to understand the implications of the current valgus angle. A pronounced valgus deformity can indeed predispose the knee to abnormal wear patterns on the cartilage, particularly on the lateral side of the patella. Over time, this can lead to conditions such as patellofemoral pain syndrome or even osteoarthritis if not addressed.

You mentioned that you have already undergone three months of strength training without improvement. This is an important consideration. While strengthening the muscles around the knee, particularly the quadriceps, can help stabilize the patella and improve function, it may not be sufficient if the underlying alignment issue is significant. If the muscle strengthening exercises have not yielded any positive results, it may indicate that the mechanical alignment of the knee is too compromised to be corrected through conservative measures alone.

Arthroscopy is a minimally invasive surgical procedure that allows the surgeon to visualize the inside of the knee joint and address any issues directly. In cases of patellar valgus, arthroscopy can be used to assess the condition of the cartilage, remove any loose bodies, and potentially realign the patella through procedures such as lateral release or medial reefing. The decision to proceed with arthroscopy should be based on a thorough evaluation of your symptoms, the degree of valgus deformity, and the presence of any cartilage damage.

The angle of valgus does indeed influence the treatment approach. A more significant angle may necessitate more aggressive intervention, as the risk of cartilage damage increases with the severity of the malalignment. If your physician has indicated that the current angle is concerning and could lead to further complications, it may be prudent to consider arthroscopy sooner rather than later.
Additionally, the timing of the surgery can also play a role in recovery and long-term outcomes. Early intervention may prevent further damage and allow for a more straightforward recovery process. Conversely, delaying surgery could result in more extensive damage that might complicate future treatment options.

In conclusion, given your situation—significant patellar valgus, lack of improvement with conservative treatment, and the potential risk of cartilage damage—it would be advisable to discuss the possibility of arthroscopy with your orthopedic surgeon. They can provide a comprehensive assessment and help determine the best course of action tailored to your specific condition. Remember, addressing the mechanical alignment of the knee is crucial in preventing long-term complications and ensuring optimal function.
